Transcript of Google Glass

Google Glass is a wearable computer with an optical head-mounted display (OHMD)

It is controlled by a touch pad and voice commands.

The output of information is displayed by the OHMD.


This device allows the user to seamlessly access and send information in a far more efficient way compared to current devices.
Importance of
Google Glass

Voice command can be problematic due to the device needing to recognise the voice of the user.

Small screen meaning only one piece of information can be show at a time.

The navigation can be inefficient if numerous applications are open.
In order to take pictures and record videos, the user must tilt their head at a certain angle. This can prove to be quite difficult.

Have to be connected to the internet

Problems with lenses
To solve voice recognition problems, the user could train the device to recognise user's speech/voice.

To solve the problem of having a small screen, a fold out screen could provide the answer to having the ability to see more than one piece of information.

Using an action (perhaps triple click), will bring up a menu presenting all the applications.
Detachable camera to avoid neck strain whilst filming.

Using smartphones' personal hotspot.

Have trained opticians to supply prescription lenses for the frame
It allows the user to:

Capture videos and pictures via the camera

Real-time information e.g weather

Speak to send messages

Customise to meet the users needs
Importance of
Google Glass
Co-operative Evaluation is seen to be best suited to review the product

Essential for designer to find out about the learnability of Google Glass

Better quality of results compared to other evaluation methods such as expert evaluation

It is also a much cheaper method

Main features to evaluate:

Usability – Time taken, tasks completed

Learnability – How easy is it to use the device

Walk-up and use – is it easy to use without any past experience

People - disabilities concerning sight would struggle using Google Glass.

Activities - Multifunctional, interface reduces cognitive load

Context – Whether it can withstand various extreme conditions (E.G rain, sun)

Technology – Real time system, different inputs for different senses.

Originality affects users perception of the product prior to using it:

No past experience

No familiarity


Clues to the user how it would be used (Norman’s definition)

Can be used for many different purposes.
